Lee Baker Bioswater Treatment Experimental Device

The "stay Baker" aeration tank is used to treat the biochemical treatment of phenolic wastewater in the gas station, and most of the active sludge method is adopted. Under the action of aeration, due to the rise of the --r during aeration, the mixture flows vertically in the pool, and the potential energy of the mixture is also made due to the potential energy of water inlet, reflux sludge, and reflux mixture, and at the same time, the mixture is also made in horizontal direction in the horizontal direction. The central water collection pipe flows according to the spiral, so that the mixed fluid flows into the second sinking pool to precipitate.

The factory has performed a test. The test results show that the volatile phenol removal rate is generally 81 % to 93 %, the COD removal rate is generally 48 % to 62 %, and the BOD5 removal rate is generally 71 % to 90 %.

Through this experimental device, I hope to achieve the following purpose:

1. Master the basic operation process of "staying Beck" biological sewage treatment device;
